Geforce Titan - GK110 will be a consumer part

The SLI results were quite disappointing, just an average of a 20% increase compared to GTX 680 in SLI.

because its havilly CPU limited in SLI

That could well be true and would represent an interesting problem for NVIDIA.

If a 4.3GHz 3820 like TechPowerUp used isn't sufficient to feed Titan SLi, what then?

whats i remember from test made by LAB501.ro, SLI of GTX 680 was limited till Core i7-3960X was not oced to 5 GHz + and Titan is more powerfull and cpu power hungry then GTX 680. Then i think for real unlimited performance SLI (2x cards) is sufficient CPU at 5 GHz + (5,5 GHz maybe)
For Tr-SLI you need 2x CPU on EVGA dual socket board at 5 GHz i think ....
